Feb. 6, 1940. A. E. COLLIS SMOKING PIPE REAMER Filed Sept. 17, 1938INVENTQR AZberZ' E. Callas WITNESSES ATTORNEYS main as shown in Fig. 2but may be easily swung over to the position shown in Fig. 1.

Instead of having a triangular shaped stem 5, a round stem 5' could beused, as shown in Fig. 7, and a keyway 15 provided into which the end ofa set screw I6 projects. present instance acts as a key and the grooveor keyway I5 acts as a guide whereby the carrier 1 may freely slide butmust rotate with the stem or plunger 5'. Also the knob 6 could be formedwith a fiat end 6', as shown in Fig. 8, and merging into a hollowextension I! having a slot l8 whereby it could fit over the end of thestem and over a suitable gear or lug so that by properly rotating themember 62 the stem will be rotated. It will therefore be seen that theknob 6 may be found and knurled, as shown in Fig.1, or may be flat andheld inplace in any desired manner either permanently or removably.

I claim: 7

l. A smoking pipe reamer comprising a stem triangular in cross section,a turning member at one end of said stem, a ball at the other end ofsaid stem, a sliding member mounted to slide back and forth along saidstem, said sliding member having a triangular-shaped aperture foraccommodating said stem whereby said sliding member may freely slideback and forth on said stem and rotate therewith, and a plurality ofspaced reaming jaws pivotally mounted at one end on said sliding member,said ball having a notch for each of said jaws for guiding the jaws asthey are moved by said sliding member, the pivotal mounting of said jawsbeing radially farther from the center of said stem than the bottom ofthe notches insaid ball whereby as said sliding members moves away fromsaid ball the outer ends of said jaws will swing radially away from eachother.

This set screw in the 2. A smoking pipe reamer comprising a stem, aspreading member at one end provided with spaced notches, a membermounted to slide on said stem but to turn therewith, a reamer jaw foreach of said notches, and means for pivotally mounting one end of eachof said jaws to said member radially farther from the center of saidstem than the bottom of said notches whereby said jaws will swinginwardly and outwardly as said member slides backand forth on said stem.

3. A'smoking pipe reamer comprising a stem polygonal in cross section, acarrier slidingly mounted on said stem and rotatable therewith, saidcarrier having a plurality of radially extending arms, a jaw for each ofsaid arms, means for pivotally connecting one end of the respective jawsto the respective arms, means at one end of said stem for guiding saidjaws and causing the same to spread when moved in one direction andpermitting the same to swing so that the outer ends will besubstantially in contact when moved in the opposite direction, and athumb-actuated member carried by said stem for rotating the stem, thecarrier and the jaws.

4. A smoking 'pipe re'amer comprising a stem triangular shaped in crosssection, a thumb member arranged at one end of said stem for rotatingthe same, a notched ball arranged at the other end of said stem, acarrier slidingly mounted on said stem and rotatable therewith, and ajaw pivotally connected to said carrier for each of said notches in saidball, said jaws being arranged to fit into said notches, the bottom ofthe notches being closer to the axis of said stem than the pivotalmounting of the jaws whereby the free ends of the jaws will be swungoutwardly as the carrier is slid toward said thumb member.
